I need to make the cells in the 1st column look like the column
header. I tried the following code but it didn't change anything:
private void rendererTest()
{
TableColumn column =
tblDecisions.getColumnModel().getColumn(0);
TableCellRenderer renderer = column.getHeaderRenderer();
column.setCellRenderer(renderer);
}
I've also tried subclassing my JTable by doing the following:
class DecisionMatrixTable extends JTable
{
DecisionMatrixTable(TableModel model)
{
super(model);
}
public TableCellRenderer getCellRenderer(int row, int column)
{
TableCellRenderer ren =
this.getColumnModel().getColumn(0).getHeaderRenderer();
if (column == 0)
{
return ren;
}
return super.getCellRenderer(row, column);
}
}
In this case I get a NullPointerException on "ren".
Help would be much appreciated.
